ARC OPTIONS
The Ranger 330MPX offers options to fine tune the arc. The
options available depend upon the weld mode.
Arc Options are
not available on the Ranger 260MPX .
TABLE B.4
HOT START - Hot Start is a temporary increase of the output
current during the start of a weld. This helps ignite the arc
quickly and reliably. Hot Start provides excellent arc ignition
without the electrode sticking and avoiding any metallurgical
default in the weld.
ARC FORCE
- Arc Force is a temporary increase in current to clear
short circuits between the electrode and the workpiece.
Lower values will provide less short circuit current and a
softer arc. Higher settings will provide a higher short circuit
current, a more forceful arc and possibly more spatter.
PINCH - Pinch controls the arc characteristics when short-arc
welding. Increasing Pinch greater than 0.0 results in a
crisper arc (more spatter) while decreasing the Pinch Control
to less than 0.0 provides a softer arc (less spatter).
PULSE, SPOOL GUN - Pulse welding with a spool gun helps to
lower heat input and create an attractive weld. Set the
frequency of the pulsing to achieve the desired effect. Slower
pulsing results in larger “stacked dimes” while higher
frequency helps to wet out the puddle. When pulsing, the
preset wire feed speed and voltage are used for the peak
values.
PULSE, TIG
- Use pulse TIG welding to help minimize burn
through on thin materials. It can help to increase travel speed
and result in a smaller bead width. Lower heat input may
lessen warpage of parts, especially stainless steel materials.
The Pulse TIG feature has a single knob control which sets the
Pulse Frequency over the range of 0.1-20 Hz (0.1-20 pulses
per second). Setting the frequency to “off” shuts off Pulse
TIG. The pulse setting automatically regulates the output
current between the peak amperage, set by the max output
control and the remote amptrol (if used), and a background
amperage setting that is equal to 50% of the peak amperage
setting. The Peak Pulse % on-time is fixed at 50%.
